The Glean dictionary aims to provide a comprehensive index of datasets generated inside Mozilla for applications built using the Glean SDK.
This project is under active development. For up to date information on project structure and governance, see:
https://wiki.mozilla.org/Data/WorkingGroups/GleanDictionary
The production version of the Glean Dictionary is deployed at:
https://dictionary.telemetry.mozilla.org
You should be able to create your own local copy of the dictionary so long as
you have Python (version 3.8+) and
node.js (version 12+) installed. You will also need npm
v7 or greater: run npm install -g npm@latest
if you need to upgrade.
Assuming those requirements are met, follow these instructions:
# Create and activate a python virtual environment.
python3 -m venv venv/
source venv/bin/activate
pip install -r requirements.txt
# Build data needed by dashboard
./scripts/build-glean-metadata.py
# Install npm dependencies and start a local
# instance of the GUI
npm install
npm run dev
If that worked, you should be able to see a local version of Glean at http://localhost:5000
You can speed up the "build data" step by appending the name of a set of application(s) you want to build metadata for. This can speed up the process considerably. For example, to build a metadata index for Fenix (Firefox for Android) only, try:
./scripts/build-glean-metadata.py fenix
We use Storybook for developing and validating Svelte components used throughout the app. To view the existing list of stories, run:
npm run storybook
To give us more confidence that changes don't unintentionally break the UI, we run storybook snapshot tests.
You can run them manually as follows:
npm run test:jest
If you intentionally made a change to a component that results in a change to the output of the storybook snapshots, you can re-generate them using the following command:
npm run test:jest -- -u
The production version of the Glean Dictionary
(https://dictionary.telemetry.mozilla.org) is deployed from the production
branch on this repository, which usually corresponds to the latest GitHub
release. To update the Glean Dictionary to the latest version, follow this
procedure:
- Do a quick test of https://glean-dictionary-dev.netlify.app to make sure it's working as expected.
- Create a new release, typically off of the
main
branch (you might find this iodide notebook useful for creating a set of notes on what changed). - From a local checkout, update the
production
branch to be in sync with the tag you just created, then push to the production branch. After the integration tests pass, dictionary.telemetry.mozilla.org should be automatically updated to the latest version.
A version of the Glean Dictionary running the development branch (main
) is
accessible at https://glean-dictionary-dev.netlify.app/
